Both are equally great... but the first one is a little more superior to the second because of the Ghouls & Ghosts series, Final Fight, & Street Fighter all packed into one game.
The second kind of digs deeper into Capcom's vault with a couple hits like more Street Fighter & Strider... but also a few lesser-known titles like Eco Fighters, Avengers, Block Block (?)... and so forth.
They're both still fun (I own both)... but the first is VASTLY superior.
